Features and Benefits
High efficiency design with low power consumption
Modular system resulting in maximum flexibility to adapt to a wide variety of applications
Extensive hydraulic options available to adapt to different process fluids
High interchangeability with five casing options on the same power end
Four high efficiency impeller options; reverse vane, closed and open impellers available
Low maintenance costs due to minimal downtime and maximized uptime
External micrometer impeller adjustment mechanism accurately sets impeller clearance in 20 seconds, in the shop or the field
Back pull-out design allows removal of rotating element without removing casing, piping or motor
High environmental and personal safety during operation and maintenance
Heavy-duty casing with integral foot and multi-ribbed discharge flange provides superior resistance to pipe loads and improves reliability
Precision cast reverse vane impeller is the only impeller design that offers repeatable pump performance throughout the life of the pump
SealSentry™ seal chamber extends seal life and provides advanced self-flushing capability
Standard non-contacting labyrinth seals keep lubricant in and contaminants out
Heavy-duty radial and thrust bearings selected for long life and reliability
Two-piece, ductile iron bearing housing is designed for safety, strength, interchangeability and retrofit capability
1935/2004/EC food grade compliant option

Configurations
CK: Closed coupled model provide a compact arrangement ideal for installations where space is a premium.
N: Centerline mounted, high pressure model is available for applications in which loads caused by thermal expansion need to be reduced.
H: Foot-mounted, high pressure model is the workhorse of chemical plants and other industries with a pressure rating up to 25 bar (365 psi).
P: Unitized self-priming model is engineered to draw from liquid sources below ground level or from sources that have no positive pressure to naturally prime the pump.
R: Recessed impeller model uses vortex action to provide low-shear pumping of friable solids and trouble-free pumping of stringy or fibrous slurries.
